EOLO BATISTONI, OF SAN FRANCISCO, CALIFORNIA.

SPRAYING APPARATUS.

To all whom it may concern.

Be it known that I, EoLo BATISTONI, a subject of the King of Italy, anda resident of the city and county of San Francisco and State ofCalifornia, have invented new and useful Improvements in SprayingApparatus, of which the following is a specification.

The invention relates to improvements in spraying apparatus which areemployed in orchards and vineyards for spraying the trees and vines withsolutions adapted to preserve the trees against the attacks of insectsand disease, and more particularly to a portable apparatus to be usedfor spraying hop vines.

The object of the invention is to provide an apparatus of this characterof a simple, effective and inexpensive construction adapted to be drawnby horses and provided with means actuated by the movement of theapparatus for effecting the spraying.

Another object of the invention is the provision of a spraying apparatuswhich can be operated to spray the vines on one or both sides of theroad or path between the rows.

A further object of the invention is to provide a spraying apparatuswhich is adapted to project a spray at all points of the tree or vine,and to project the spray over several rows of vines on either side ofthe road or path at the same time.

In the culture and raising of hops a series of rows are planted closetogether and a path or roadway is provided between adjacent groups ofrows. During the growth of the plants they are arranged on frames ortrellises, so that the area between the roadways are more or lesscovered with the vines. To properly treat all of the vines it isnecessary to project the spray longitudinally at the vines along theedge, and to project it over and onto the vines in the center The sprayentering the cluster of vines longitudinally penetrates to the center ofthe cluster effectively treating the lower parts of the vines, and thespray from the upper nozzles is effective on the upper parts of thevines.

In spraying the vines along one edge of the field it is necessary toconfine the spraying operation to one side of the road, and in thepresent device I have provided means operative by the driver of thevehicle for adjusting the sprays to meet the conditions. When a vineyardis attacked by disease the Specification of Letters Patent.

Serial No. 550,906.

affected portions are generally isolated and the vineyard as a whole isnot attacked. It is evident, therefore, that itis advisable to have somemeans to convenient-1y regulate the sprays, so that the sprayingsolution need be applied only to the infected spots and not to the wholevineyard.

To these objects the invention consists of a vehicle having the sprayingappartus arranged thereon, and adapted to be operated by the motion ofthe vehicle and provided with means within reach of the driver forregulating the spray on either side independently.

The following description explains at length the nature of my saidimprovements and the manner in which I proceed to apply the same in theproduction of a spraying apparatus, reference being had to the drawingsaccompanying this specification.

Figure 1 is a side elevation of the complete apparatus, the tongue andWhittle-tree being removed from the vehicle. Fig. 2 is a longitudinalsection through the containing and pumping apparatus. Fig. 3 is a planview showing the relative positions of the various parts. Fig. 4 is anend view. Fig. 5 is a detail plan view of one pair of the spraying arms.

In constructing a spraying apparatus in accordance with my invention,the vehicle frame 2 of suitable form and strength to support the severalparts is mounted on the wheels 3 and is provided wit-h the proper poleor tongue for the attachment of the draft animals. A receptacle,preferably a Wooden tank or barrel 4 is mounted on the vehicle frame 2,and is adapted to contain a supply of the solution to be sprayed. Thetank 4 is provided with a funnel-shaped opening 5 at the top, so thatthe fluid can be conveniently poured in.

The necessary pressure to operate the sprays is obtained from theforce-pump 6, located on the vehicle frame, and supplied With liquidfrom the supply tank 4, through the feed pipe 7. The pump 6 is drivenfrom the rear axle 8, which revolves with the rear wheels, by means ofthe drive chain 9 and the sprocketwheels 1011. The sprocket-wheel 11 ispreferably mounted on the vehicle frame in line with the pump, so thatits motion can readily be transferred to the pump piston 12. A clutch,operated by the lever 14 is provided so that the pump may be readilydisconnected from the running gear when it is desirable to transport theapparatus from place to place without operating the sprays. A seat 15for the driver and operator is provided at the rear of the vehicle insuch position that the lever 14 can be easily reached.

From the pump 6, the solution is forced into the pressure tank 16 fromwhence it passes through the valve 20 into the pipe or hollow mast 17.For the purpose of preventing the pressure in the pressure tank 16increasing beyond the desired limit and throwing too great a strain onthe pump, I employ a by-pass or return-pipe 18, provided with a reliefvalve 19. lVhen the pressure within the tank 16 rises above the desiredpoint, the relief valve 19 is automatically opened, and the solutionreturns to the supply tank 4 through the pipe 18. A pressure gage 21 isalso provided to allow the operator to observe the pressure in the tank16.

The hollow'mast 17 is made of any desirable height, according to theWork to be accomplished, and is held in position by the guy-Wires 22attached to the frame of the vehicle. At intervals apart vertically ofthe mast 17 are arranged the longitudinally extending hollow arms orpipes 23, carrying the sprayer nozzles 24. The length of the arms 23 isincreased toward the upper end of the mast, so that the nozzles on theupper arms are spacedfarther apart than those below. I have preferablyarranged three nozzles on each of the arms; one at each end and one inthe middle to spread the spray over a greater area. The arms 23 arecon.- nected to the hollow mast 17 on each side through the spring heldvalves 2526 which are held normally closed by an inclosed spring.

The valves 2526 are operated by the movement of the arms 2728. The armsare connected to wires or cords 30 and are adapted to be operated by themovement of the levers 2931 respectively through the medium of the wires32-33, the bell-cranks 34-35 and the wires 30. The nozzles on one sideare therefore controlled by one of the levers 29 and on the other sideby the other lever. 31 and the driver of the vehicle is enabled'toregulate the spraying operationrfrom the drivers seat, and to confinethe spray to either side of the roadway according to the varyingconditions. The nozzles 24 project the spray at right angles to thedirection of travel of the vehicle and nally extending arms 23 andthereby varying the distance between the nozzles at the differentheights, a broadside spray is obtained, covering an area equal in onedimension to the distance between the most widely spaced nozzles. Thisarrangement is more clearly shown in Fig. 3, the distances between thevertical projections of the nozzles being approximately equal.

It is understood that I do not limit myself to the exact means shown foraccomplishing the various results as many changes could be made in theapparatus without varying from the spirit of my invention.

I claim 1. In a spraying apparatus, the combination of a vehicle, ahollow mast, pairs of spray pipes arranged longitudinally of saidvehicle and spaced apart vertically on the mast, the spray pipes of eachpair being arranged on opposite sides of the mast, the length of thespray pipes increasing with the distance above thevbase of the mast, andlaterally projecting nozzles at the middle and ends of each of the spraypipes.

2. In a spraying apparatus, the combination of a vehicle, a liquidsupply-tank thereon, a pressure tank, means for forcing the liquid intothe pressure tank, a vertical pipe connected to the pressure tank,horizontally disposed spray-pipes arranged longitudinally of the vehiclein pairs on opposite sides of the vertical pipe, a valve between eachspray pipe and the vertical pipe, laterally projecting horizontalnozzles on each spray pipe and means within reach of the driver of thevehicle for independently regulating the sprays on opposite sides of thevertical pipe.

3. In a spraying apparatus, the combination of a vehicle, a liquidsupply tank thereon, a pressure tank, means operated by the running gearfor forcing the liquid into the pressure tank, a pipe connecting thepressure tank with the supply tank, a valve in said pipe operated by anexcess of pressure in the pressure tank to allow part of the liquid toreturn to the supply tank, a vertical pipe connected to the pressuretank, spray pipes arranged longitudinally of the vehicle in pairs onopposite sides of the vertical pipe, the length of the spray pipesincreasing with the distance from the base of the vertical pipe,laterally projecting nozzles on the spray pipes, valves between thespray pipes and the vertical pipe, and means within reach of the driverof the vehicle for simultaneously operating all of the valves on eitherside of the vertical pipe.
